HEATING DEVICE.

Specification of Letters Patent.

Patented Mar. a, left.

Application filed July 27, 1914:. Serial No. 853,462.

To all whom it may concern Be it known that I, WILLIAM J. FRANK, a citizen of the United States of America, and a resident of Webster Groves, in the county of St. Louis, State of Missouri, have invented certain new and useful Improve ments in Heating Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in heating devices, more specifically stated, to a receiver for cooking utensils adapted to confine the flame and hot air arising from a stove burner, the object being to confine the heat around the bottom and sides of the cooking utensils.

The preferred form of the inventlon consists of a receiver in the form of a flue open at the top to receive a cooking utensil and open at the bottom to receive the flame and hot air rising from a burner.

Figure l is a top or plan view of a receiver embodying the features of my invention. Fig. H is a vertical section of the device shown in Fig. I, a cooking utensil and a portion of a stove being shown by dotted lines. Fig. 111 is a detail view of he grate sections shown in Figs. 1 and II.

In the accompanying drawings: A designates a receiver which is preferably a conicocylindrical flue formed of sheet metal reinforced by an annular wire 1 at its upper edge and a similar wire 2 at its lower edge. The receiver A is open at the top to receive a cooking utensil B and openat the bottom to receive the flame and hot air rising from a stove burner C, the receiver being seated on the grating G which forms part of the stove.

D designates a support for the cooking utensil, preferably located ad acent the lower end of the receiver and preferably secured to the circular wall of said receiver. The support I have shown comprises a pair of intersecting grate bars 8 extending across the lower portion of the receiver, interlocked with each other at the point of intersection and having their ends interlocked with the receiver.

The middle portion of each grate bar 3 Copies of this patent may be obtained for is preferably provided with a transverse notch at adapted to receive the other grate bar, and the ends of each grate bar are preferably provided with notches 5 forming fingers 6 which engage the outer face of the receiver as shown most clearly in Fig. III. Slots 7 are formed in the receiver A at the ends of the grate bars 3, and it will be noted that the ends of the grate bars may be readily inserted into these slots and then forced downwardly to firmly interlock the grate bars with the receiver. When the intersecting grate bars are interlocked with each other, their top faces lie in a common horizontal plane to form a horizontal seat for the cooking utensil, and since the ends of the grate bars are securely interlocked with the sheet metal receiver, the latter is materially reinforced by the grate structure as well as by the reinforcing wires 1 and 2.

I claim:

1. A device of the character described comprising a flue member open at the top to receive cooking utensils, and open at the bottom to receive the flame or hot air passing from a stove burner, and a grate eX- tending across the lower portion of said flue member so as to form a seat for the cooking utensils, said grate being composed of intersecting grate bars interlocked with each other at the point of intersection and having their ends interlocked with said flue memher.

2. A device of the character described comprising a receiver consisting of a conicocylindrical sheet metal flue member provided with annular reinforcing wires at its top and bottom edges, said flue member being open at the top to receive cooking utensils and open at the bottom to receive the flame and hot air passing from a stove burner; combined with a pair of intersecting grate bars extending across the lower portion of said flue and forming a seat for the cooking utensils, said grate bars being interlocked with the flue member at their ends and interlocked with each other at the point of intersection.

WILLIAM J. FRANK.
